  • Procedure: Resection surgery
    After week 18, participants will undergo standard of care resection surgery.

    Experimental: Expansion

    An additional 22 participants will be enrolled at dose level 2 if determined to be safe in lead in phase to have a total of 28 evaluable participants for pathologic response assessment (including 6 pts from the lead in phase).

    Biological: HER-2 pulsed DC1
    Vaccine will be administered weekly for 6 weeks. Boosters will be given at months 6, 9 and 12.

    Outcome Measures

    Primary Outcome Measures

    1. Lead in Phase: Immunogenicity of each dose level [at 4 weeks]

      Immunogenicity: will be characterized by quantifying CD4TH1 response via ELISPot. ELISPot is an enzyme-linked immunospot assay. It is a highly sensitive immunoassay that measures the frequency of cytokine-secreting cells at the single-cell level.

    2. Expansion Phase: Pathologic Complete Response Rate [at 12 months]

      Pathologic complete response rate of participants treated in the Expansion Phase. Clinical efficacy will be defined by the pathologic complete response (pCR) rate, the percentage of patients who achieve pCR based on surgical pathology assessment. Pathologic Complete Response defined as no residual invasive disease in the breast and nodes (ypT0/is N0) at definitive surgery after completion of protocol therapy. The pathologic response to treatment will be assessed by the pathologist. The "Residual Cancer Burden" (RCB) for each patient as described in the online calculator also will be evaluated per the pathologist.

    Secondary Outcome Measures

    1. Expansion Phase: Radiologic tumor response rate after 6 weeks [at 6 weeks]

      Radiologic tumor response rate measured by MRI

    2. Expansion Phase: Radiologic tumor response rate at completion of therapy [at 12 months]

      Radiologic tumor response rate measured by MRI

    3. Expansion Phase: Immunogenicity [at 12 months]

      Immunogenicity: will be characterized by quantifying CD4TH1 response via ELISPot. ELISPot is an enzyme-linked immunospot assay. It is a highly sensitive immunoassay that measures the frequency of cytokine-secreting cells at the single-cell level.

    4. Recurrence Free Survival [up to 3 years]

      Recurrence free survival defined as the length of time after treatment that patient survives without any signs or symptoms of cancer.

    All
    Accepts Healthy Volunteers:
    No
    Inclusion Criteria:
    • Participants must have histologically confirmed clinical stage I- III, HER2+ (per ASCO/CAP criteria) invasive carcinoma of the breast. Primary tumor should measure at least 1 cm by clinical exam or radiologic tests

    • Patients may not be receiving any other investigational agents for the treatment of their breast cancer.

    • History of allergic reactions attributed to compounds of similar chemical or biologic composition to the study vaccine components and any of the chemotherapy drugs (paclitaxel, trastuzumab, pertuzumab).

    • Participants who are unwilling or unable to undergo an apheresis for production of their vaccine.

    • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

    • Pregnant women and women who are breastfeeding.

    • Participants with known congenital or acquired immune deficiency (including those patients who require systemic immunosuppressant drugs for autoimmune disease or organ transplant).
